    摘要: A hammer drill has a three-part hammering sleeve. A hardened tool socket is attached to a guide tube made of unhardened steel by an axial connection. For connection to the driving gearwheel, the guide tube furthermore carries a latching ring fixed on the guide tube by three rollers which make possible good torque transmission. This construction has the advantage that it is no longer necessary to harden the entire hammering sleeve but only the tool socket and the latching ring. The guide tube can be composed of soft steel. The connections and ensure large-area transmission of force, wear on the soft guide tube caused by conventional connection techniques thereby being avoided.

    摘要: A hammer drill is provided with a clutch whose movable part is firmly connected to an axially displaceable drum which supports a wobbling disc driving a percussive mechanism for striking a work tool. The axially fixed clutch part is rotated by driving motor and is backed-up by a housing of the drill. Retroacting forces from the percussive mechanism are transferred via the drum onto the movable clutch part so that the engagement of the clutch is reinforced at the moment when the compression generated by percussive mechanism is maximum. When pressure applied on work tool is relieved, a separating spring disengages the clutch and braking surfaces on the drum limit its axial displacement and brake the rotation of the wobbling disc.

    摘要: An impact hammer has a housing, a motor accommodated in the housing, an impacting mechanism accommodated in the housing and having a driver and a striker which is displaced by the driver in an axial direction and periodically strikes a shaft of a tool with the driver being tiltable about a tilting axis, a driving element which drives the driver into a reciprocating motion and a shaft which rotates the driving element. The driving element is provided with two interengaging eccentric parts including a first eccentric part which is non-rotatably connected with the shaft and a second eccentric part which is axially displaceable relative to the shaft. The eccentric parts have ring surfaces each surrounding the shaft, arranged asymmetrically relative to one another and being in contact with one another. The ring surfaces are offset relative to the one another so that a resulting eccentricity of the driving element relative to the shaft, which eccentricity acts on the driver, is adjustable between zero and a maximal value.

    摘要: In a motor driven circular saw, a saw blade drive is provided, by which a rotary movement of a saw blade, supported on a rotary blade shaft, is superimposed by a back and forth-movement in the direction of sawing to produce a forward stroke and a backward stroke of the blade and to thus improve cutting efficiency of the saw. The saw blade drive includes a pinion at the end of a motor shaft, a first gear meshed with the pinion and supported on the saw blade shaft, a second gear meshed with the first gear and having a cam and eccentrically positioned together with the cam on a stationary axle. A coupling rod connects the cam with the saw blade shaft to impart to the latter the back-and-forth movement.

    摘要: A hammer drill is provided with an accessory that is rotatably supported on the chuck of the drill and has a handle fixed to the support rotatable on the drill chuck. Structure is provided forming a throughgoing passage extending from the tool through the handle to the outer end of the handle and a flexible conduit is connected to this handle at the outer end thereof for drawing gas and particles from the tool through the passage. The structure may surround an intermediate portion of the tool at the radial opening of an axial bore through the tool so that particles and the like can be aspirated directly through the tool. Alternately a telescoping tube is provided connected at its rear end to the passage at the support and at its front end to a cup through whose base the drill passes, so that this cup is pressed against the workpiece during the drilling operation.

    摘要: An impacting drill is equipped with an air cushion impacting mechanism and with a tumbling mechanism which is operative for reciprocating the impacting mechanism. The tumbling stroke of the tumbling mechanism and thus the reciprocating stroke of the impacting mechanism is adjustable from zero to a maximum. The tumbling mechanism includes a hub body which is mounted on a holding body rigid with a rotatable shaft. The holding body is centered on an adjustment axis which encloses an acute angle with the axis of the shaft. The hub body is mounted on the holding body for angular displacement about the adjustment axis with attendant adjustment of the tumbling range. Coupling elements connect the hub body with the holding body in the respectively selected angularly displaced position of the hub body on the holding body. There may be provided a stepping switching mechanism between the hub body and the holding body of the shaft, by which an axial displacement of the shaft is converted into angular displacement of the hub body about the holding body.

    摘要: A hand-held power tool with an electric drive motor, by means of which a rotary sleeve impacting upon a tool retainer holding a tool can be rotatably driven by a transmission, and by means of which an impacting mechanism can furthermore be driven. The power tool includes an axially oscillating drive piston, an impactor impinged by the drive piston over an air cushion which will transmit its impact energy onto the tool. A translation drive acts upon the drive piston with a rotatably driven drive member with a curved guide. At least one actuator follows the curve guide and acts upon the drive piston to effect its axial displacement. The drive member consists of a drive sleeve coaxial with and concentrically enclosing the drive piston and the impactor. The drive sleeve has a guide surface closed in itself in the circumferential direction and has an essentially steadily rising or falling incline with curve maxima and curve minima. The actuator is designed as a separate and freely movable rolling or sliding body and is in immediate contact with the drive piston at a location adjoining the guide surface. The rolling or sliding body is prevented from deviating along the guide surface by means of a positive retainer securing these like a cage, but held in the axial direction with a degree of freedom required for following this guide surface.

    摘要: A portable machine tool, especially a hammer drill, mainly comprises a housing in which a guide tube is arranged. A piston and a beater are guided in the guide tube reciprocatable in axial direction, the piston and the beater having facing axially spaced ends forming therebetween in the guide tube an air pillow through which the impact energy of the piston is transmitted to the beater. A turning sleeve coaxially surrounds the guide tube and is provided at its front end with a holding bushing formed with a coaxial bore therethrough in which a shaft of a tool, for instance a drill, is mounted for rotation therewith and for limited axial movement relative thereto. The beater is provided at the front end with a beater bolt having an outer diameter slightly smaller than the inner diameter of the bore so that the beater bolt, which transmits its impact energy directly to the free end of said tool shaft, may enter into the bore to be guided therein during reciprocation of the beater.
